When I specify multiple python versions like below, travis initiates testing.

```
python:
  - "3.7"
  - "3.8"

```

(from [https://github.com/biocommons/uta-align/blob/05a6d088d66ce911e934b1c085c173fdefd65a7b/.travis.yml](https://github.com/biocommons/uta-align/blob/05a6d088d66ce911e934b1c085c173fdefd65a7b/.travis.yml))

If I remove either version line so that only one version is specified, travis (nearly) silently ignores the push. The requests page shows “Build config did not create any jobs.”

If I specify 3.7 twice, it works but initiates only one 3.7 run.

Both of these behaviors surprise me.

In [https://github.com/biocommons/uta-align/blob/43cd96db6956f45fa1b7f6a3affe9b1ad3e436bd/.travis.yml](https://github.com/biocommons/uta-align/blob/43cd96db6956f45fa1b7f6a3affe9b1ad3e436bd/.travis.yml) the explicit job definition is invalid due to password specified incorrectly.

The job from matrix is not created because [https://docs.travis-ci.com/user/build-matrix/#explicitly-included-jobs-with-only-one-element-in-the-build-matrix](https://docs.travis-ci.com/user/build-matrix/#explicitly-included-jobs-with-only-one-element-in-the-build-matrix).
